孤立波对复式斜坡堤上行人冲击作用研究
Study on impact of solitary waves on pedestrians on composite slope seawalls
摘要
Abstract
In response to the issue that extreme waves posed a serious threat to pedestrian safety on coastal composite sloping revetments,a quantitative investigation was conducted into the force characteristics of pedestrians under such hydrodynamic environments.A three-dimensional viscous-flow numerical wave-flume model was established on the OpenFOAM platform,a 185 cm standard human-body model was scaled down,solitary waves were adopted to simulate extreme-wave conditions,and physical model tests were combined to verify the reliability of the numerical method.The study focused on analysing the force characteristics of pedestrians in the revetment-protection region of the composite sloping revetment.Results show that the ratio of the return-flow force to the impact force varies with the relative position of the human body in an exponential-function form,whereas its relationship with the relative unit-width discharge follows a power-exponential function.The impact force is increased with increasing wave height,while the increment of the backflow force tends to flatten out.On this basis,a force formula for pedestrians on the revetment was derived,and the prediction error was basically controlled within 20％.关键词
